Officers smelled marijuana in the car, then went to his apartment nearby in the 1700 block of West Fourth Place and smelled marijuana there as well, said Kennewick police Sgt. Ken Lattin.

Detectives with the department's Criminal Apprehension Team then got a warrant to search Pourier's apartment, and that's when a small bomb was found inside a safe.

Officers left the apartment and called out Richland police's Bomb Squad.

Bomb technicians were able to disable the pipe bomb using mechanical means, said Richland police Capt. Mike Cobb.

Pourier was arrested and booked into the Benton County jail early Sunday on suspicion of possessing an explosive device, two counts of being a felon in possession of a firearm and possessing marijuana.

Semi crashes into another trailer on Highway 221 near Paterson

A semi-truck crashed into the trailer from another semi-truck that blocked part of Highway 221 near Paterson early Monday, the Washington State Patrol said.

Evaristo C. Milanez, 65, of Prosser, was driving a 1989 Freightliner semi-truck southbound on highway from a private driveway when he lost his trailer, causing it to partially block the northbound lane, troopers said.

Vance V. Hubbard, 36, of Middleton, Idaho, was in a 2007 Volvo semi-truck that was going north on the highway and struck the trailer.

Hubbard was treated at Kennewick General Hospital. Milanez was not hurt.

Troopers said defective equipment was the cause of the 5:24 a.m. wreck.

Texas man injured when semi crashes into truck on Highway 14

A 61-year-old Texas man was hurt Monday when a semi-truck crashed into the back of his pickup on Highway 14 south of Kennewick, the Washington State Patrol said.

Eleazar Rodriguez, 61, of Maverick, Texas, was taken to Kennewick General Hospital for treatment.

Rodriguez was driving a 1992 Ford Ranger pickup, heading westbound on Highway 14, about 18 miles south of Kennewick, when he was hit by the semi-truck, troopers said.

The semi, driven by Tony Cedillo, 25, of Hermiston, also was going west on the highway.

Rodriguez slowed to make a left turn, and that's when the semi rear-ended him.

Troopers said the cause of the 11:30 a.m. wreck was Cedillo following too close in the semi.
